Fans are buying up copies of this crucial extender for Evil HERO in anticipation of Supreme Darkness coming to the TCG, possibly in 2025
(Youll see me refer to the late 90s a lot in this post, so Ill just let it be known now, that when I say the late 90s Im referring to 1998 -1999.) So, if you were actively buying card packs or begging your parents to buy them (like I was) every time they went out and you happened to obtain this card, you could be sitting on at least $10,000
For example, a Pikachu could suddenly become a Fire-type Pokmon
One of these recently sold for over $20,000
If you want a decent copy but aren't thrilled at the idea of spending over $100, you can find MP cards closer to $90, though LP jumps into the $105 range.
